Former Sigma Nu member Joaquin Mendoza will not face charges following sexual assault accusations, according to the State Attorney Office.

"We declined to file charges in the case because the evidence was not suitable for prosecution. Alcohol was involved and memories were impaired, which made it difficult to know all of the facts," Orange County State Attorney Office spokeswoman Angela Starke said Tuesday.

Mendoza was accused of sexually assaulting a woman at the fraternity's off-campus house and in her dorm room. State Attorney Office documents state that both Mendoza and the victim were drinking, and that the victim could not recall exactly what had happened but had pieced together information from what she could remember as well as information from witnesses.

The morning of Oct. 3, the victim awoke "completely nude and in a lot of pain and very sore," according to a report from the UCF Police Department. The victim discovered an open condom wrapper and condom on the ground.

UCF documents showed that in a June incident, Mendoza was also reportedly caught on video chanting "rape" and sexual comments. But a UCF Student Conduct panel found there was also insufficient information to suggest that Sigma Nu, as a fraternity, was responsible for Mendoza's remarks.
